Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh or humid industrial environments.
- Excellent holding power and load distribution thanks to the wide truss head design, reducing the risk of material pull-through.
- Efficient, self-tapping installation with thread-forming (Type A/AB) design, creating strong threads in sheet metal without a pre-tapped hole.
- Secure and reliable drive engagement with the Phillips No. 1 drive, minimizing cam-out during installation.
- Full-length threading for maximum grip and fastening strength along the entire 3/8" length in sheet metal applications.
- Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial supply chains.
- Precision-engineered dimensions (e.g., 0.257" head diameter, 24 TPI) for consistent performance and interchangeability.
Professional Applications & Engineering Value
This 316 stainless steel tapping screw is engineered to solve common fastening challenges in sheet metal assembly. Its thread-forming (Type A/AB) design displaces material to create strong, clean internal threads, eliminating the need for pre-tapping and speeding up production. The wide truss head provides a larger bearing surface, which helps prevent the screw from pulling through thinner gauge metals and distributes clamping force more effectively. Made from 316 stainless steel, it offers exceptional resistance to corrosion from chemicals, saltwater, and industrial atmospheres, making it a reliable choice for HVAC systems, electronic enclosures, and outdoor equipment. The combination of a Phillips drive and a pointed tip ensures straightforward installation with standard tools, enhancing assembly efficiency and joint integrity in demanding applications.
Specification Summary & Compliance
This screw conforms to standard inch dimensions: No. 4-24 thread size, 3/8" length, and a Class 2A thread fit. It is a fully threaded, right-hand thread forming screw (Tapping Screw Type A/AB). The product is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety standards for industrial components.
